IMPROVEMENT 1N PLoUeus. t

TO ALL WHOM IT MAY CONCER-N: i

Be it known that I, CHARLES Fonsrnn, of Lebanon, in the county ot Lebanon, and Stateof Pennsylvania.; have inventeda new and useful Improvement in Ploughs; and I do hereby declarethat the` following is a. full)` clear, andexact description thereof, which will enable others skilled in theartto makeandusethe same, reier-` ence being had to the accompanying drawings, forming part of `this specification. Figure 1 is a side view of my improved plough. i l i r Figure 2 is thesame view as fig. 1, the shear-cutter and land-side being removed. Figure 3 is a detail view of the land-side detached from theplough. l Figure 4 is a. detail view of the inner side of the cutter. Figure 5 isa detail vtop view of the shear. Similar letters of reference indicate corresponding parte. t My invention has for its .object to improve the manner inwhich the cutter and land-sidelare connected'to` l each other and to the standard and mould-board, so asito make the connection stronger, firmer, and more secure; and it consists in forming grooves or recesses in the standard or forward end of the mould-board to receive they;

of the iiaugc upon the forward end of' the land-side to receive a projection formed upon the inner"` side of the` rear part of the cutter; the whole being-constructed and arranged as hereinafter more fully described. i i ,y A are the handles, B is the beam, Cis the standard, and D is the mould-board of the plough. The standard l i, C and mould-board-D may, if desired, be c ast in one piece, as shown in figtZ. Upon the side of the stendardi `3 C i`s formed a recess or shoulder to receive the ange e of the land-side En Atthe point where 'the upper bolt` 7 passes through, the recess el of the standard C is extended, as shown at the` point c indig.` 2,7to receive the-i` tongue e? formed upon thel iiangc el, through which the said` bolt passes. Upon-the side of the flange elisl formed a recess or groove, e3, to receive a projection, f', formed upon the inner 4side of the rear` partlof the; cutter F to make the connection between the cutter and 1and-side stronger. Upon the `inuersidefot" the flange; i el of the land-side E, exactly opposite the `recessa, is formed a projection to strengthen ,the angelelthat would otherwise be weakened bythe formation of the recesses, making that part as strong, or stronger than any other t i i part of the said auge. F is the cutter, which is fitted tothe standard C and `to the land-side E, so Athat the, outer surface of the said cutter and land-side maybe in the same plane. The cutter, land-side, and mould-board`n are secured together by bolts, the upper bolt passing through the mould-,board D, `tongue c of the fiange eof 1` the land-side E, and through the cutter F. The lforward lower bolt passes through the mould-board and cutter,"i

land the rear` lower bolt through the 1and-side and cutter, as shown in igs. 1 and .2... is the shear, which is l bolted to the mould-board D and to the handles` A in the usual manner, `being also secured tothe beam Bby l, ,l the `long bolt H. By this construction the cutter, land-side, andmould-board are rmlyand strongly securedi l together so as to be able to resist any strain that may be brought upon them, andrso as to be easily detached and removed, when desired. 4 l

I claim as new, and desire to secure by Letters Patent-ll i 1. Forming recesses el c2 in the standard C or forward end of the luould-board D to receive the `flange el V and tongue rez-formed upon the forward end of the landside E,substantially as herein shown and described and i i for the purpose set forth. i ,l

2. `Forming a recess or groove, es, in the outer side of the ange e1 of the laudside E for the reception of'` n i the projection j formed upon the inner side of the rear part of the cutter F, substantially as herein shown `and .i i l l cHARLns ronstrrn.A Witnesses ANTHONY S. ELY, THOMAS Fons'rnn.
